Question

我在列表中有一个带有serval复选框项的表单。我有一个这个列表的编辑器。它们在屏幕上显示很好。但提交时，检查的项目未在模型中提交......

型号：

public class ContactUsersModel : BaseModel
{
     public IList<FilterCheckModel> PreviousVisitors { get; set; }
}

public class FilterCheckModel : BaseModel
{
    public string Name { get; set; }
    public string Value { get; set; }
    public bool IsChecked { get; set; }        
}

控制器：

IList<FilterCheckModel> prevVisitList = new List<FilterCheckModel>();
prevVisitList.Insert(0, new FilterCheckModel() { Name = "All previous visitors", Value = "0" });
prevVisitList.Insert(1, new FilterCheckModel() { Name = "Not visited in last month", Value = "1" });
prevVisitList.Insert(2, new FilterCheckModel() { Name = "Not visited for 1-3 months", Value = "2" });
prevVisitList.Insert(3, new FilterCheckModel() { Name = "Not visited for 3-6 months", Value = "3" });
prevVisitList.Insert(4, new FilterCheckModel() { Name = "Not visited for over 6 months", Value = "4" });
model.PreviousVisitors = prevVisitList;

HTML：

 <table>
       <tr>
         <th>
             Previous visitors:
         </th>
       </tr>
       @for (int i = 1; i < Model.PreviousVisitors.Count; i++)
       {
           @Html.EditorFor(model => model.PreviousVisitors[i], "FilterCheck", new { Index = i + 1})
       }
  </table>

编辑：

<tr>
    <td>
        @Model.Name
    </td>
    <td>
        @Html.CheckBoxFor(x => x.IsChecked)
        @Html.HiddenFor(x => x.Value)
    </td>
</tr>

Answer 1

发现它！

原因是在我的循环中我开始i = 1。由于某种原因，这会导致问题。索引需要从0开始...

  @for (int i = 1; i < Model.PreviousVisitors.Count; i++)

所以我将其更改为

  @for (int i = 0; i < Model.PreviousVisitors.Count; i++)

它有效！
